Actually I am having the reverse problem. I have a really good
local dealer where I can buy cheap ingots of any of a wide variety of
aluminium alloys. My problem is I cant find much information on the
differences in casting of the different alloys. I have been able to find
material on *machining* the metals but little on *casting* difference.
